No Delete button for terrain layers. + Unclear UI

[beo6]

I found the Terrain tools a bit unintuitive.

1. Its not really clear, what the upper Buttons belong to. You first think, its to load a material for the layers, not for the terrain heightmap itself.

2. Once you added a Layer and you then notice you don't need it, there is no way to delete it again. Only Replace it with another one. (Or i just haven't found any way).
